first time boot problem after installation

Question

hi, this is my frst post here in this forum, today i installed OSX Maverick 10.9.0 on my system, the system specs is:

intel i7 2600k

asus maximus iv gene z

asus dc cu II gts 680

kingston hyperx blue 2 x 4gb

750 gb WD black HD,

after successful installation on reboot:

first time i got a panic saying system up time in ..... nano seconds,

then i used -v and -x while booting and everything worked fine and the the white screen with apple logo appears and stucked, then i restarted the pc and used -v -F and GraphicsEnabler=No thn still the stucked at the same white screen and apple logo...

I have never experienced the error "Couldn't find IOSurfaceRootUserCleint for task" before but in the verbose log, the prelinked kernel has expired, you can try rebuilding it by booting in Single user mode
boot with kernel flag -s
#Run the following commands one by one
mount -uw /
kextcache -i /
reboot
Let me know the results

First problem - After playing a video on any player, only the sound is played and the picture will not be displayed. I tried different settings with VLC but the image is still not.
The second problem - In Safari is scrolling OK, in Chrome the image is jerking for scrolling.
Default is Sierra after installing with HD 7000, does not help changing to HD 630
Is there anything else to do with the graphics card ?
I have already written in the forum but no one can help me. Help me please.
